Multiscale methods for solving wave equations on spatial networks
Morgan Görtz, Per Ljung, Axel Målqvist
We present and analyze a multiscale method for wave propagation problems, posed on spatial networks. By introducing a coarse scale, using a finite element space interpolated onto t…

Iterative solution of spatial network models by subspace decomposition
Morgan Görtz, Fredrik Hellman, Axel Målqvist
We present and analyze a preconditioned conjugate gradient method (PCG) for solving spatial network problems. Primarily, we consider diffusion and structural mechanics simulations…
